The spectroscope includes a wavelength-selective interference filter on which light from a measurement target is incident, and the carriage moving unit moves the spectroscope in an X direction with respect to the measurement target. If the measurement target is a color patch, the spectroscope performs spectrometry by changing a wavelength of light passing through the wavelength-selective interference filter in a first period during which the spectroscope is moved in the X direction, and passes light of an initial wavelength through the wavelength-selective interference filter at a start of measurement and at an end of measurement in the first period. A first output value that is a measured value from the spectrometry at the start of measurement is compared with a second output value that is a measured value from the spectrometry at the end of measurement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spectrometry device, image forming apparatus, and spectrometry method","description":"A printer includes a spectroscope and a carriage moving unit.
